Technical Field

[0001] This utility model relates to the field of road measurement technology, and more specifically, to a special measuring device for road engineering design. Background Technology

[0002] During the construction of roads, it is usually necessary to use a theodolite to measure directions and angles.

[0003] When measuring, theodolites are placed using a tripod to ensure stability on the road surface. However, existing tripods are inherently too long to easily fit into containers for storage, making them cumbersome to transport. Consequently, the difficulty in storage and transport reduces measurement efficiency when measuring in different locations along the road. Utility Model Content

[0004] The purpose of this utility model is to provide a special measuring device for road engineering design, which solves the problem that when theodolites are used to measure roads, the length of the tripod makes it difficult to put them into a container for storage, making them too troublesome to move.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a special measuring device for road engineering design, including a base, a support connected to the bottom of the base, a combined rod connected to the middle of the support, a hinge shaft provided at the top of the combined rod, a sleeve ring provided at the bottom of the combined rod, and an interlocking component provided between the combined rods.

[0007] Preferably, the support is composed of several connecting rods.

[0008] Preferably, the combined rods are connected by a sleeve ring and a hinge shaft. Both the sleeve ring and the hinge shaft are located on one side of the end face of the combined rod, and the sleeve ring and the hinge shaft on each combined rod are arranged in opposite directions.

[0009] Preferably, the combination rod further includes a connecting groove, a connecting block, and a stop block. The connecting groove is located on one side of the combination rod, the connecting block is located on one side of the combination rod, and the stop block is connected to both sides of the connecting block.

[0010] Preferably, the connecting grooves on both sides of each composite rod are positioned opposite to the connecting blocks.

[0011] Preferably, the abutment is a trapezoidal block connected to the grooves on both sides of the connecting block by a spring, and the abutment cooperates with the grooves on both sides of the middle of the connecting groove.

[0012] Preferably, the fitting assembly includes a limiting groove and a limiting block, the limiting groove being disposed on the bottom side of the combined rod away from the sleeve ring, and the limiting block being disposed on the top side of the combined rod away from the hinge axis.

[0013] Preferably, the limiting block is provided with abutment blocks on both sides, and the limiting block cooperates with the limiting groove.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] 1. The combination rods in this device allow the bracket to be connected in sections, and the length of the bracket can be shortened by folding the combination rods, making it convenient to store and transport the bracket.

[0016] 2. The device is also equipped with a fitting component, which limits the state of the combination rod when it is unfolded and folded, preventing the combination rod from deflecting on its own. Attached Figure Description

[0022] The following is combined with Figures 1 to 4 This utility model will be described in detail.

[0023] A special measuring device for road engineering design includes a base 1, a support 2 connected to the bottom of the base 1, a combined rod 201 connected to the middle of the support 2, a hinge shaft 202 provided at the top of the combined rod 201, a sleeve ring 203 provided at the bottom of the combined rod 201, and an interlocking component provided between the combined rods 201.

[0024] First, the theodolite for road surveying is installed on base 1. Then, base 1 unfolds into a triangular support frame through the bottom bracket 2, so that the theodolite can be stably placed on the road for road surveying.

[0025] Furthermore, the bracket 2 is composed of several combined rods 201 connected together. The combined rods 201 are connected to each other by a sleeve ring 203 and a hinge shaft 202. The sleeve ring 203 and the hinge shaft 202 are both located on one side of the end face of the combined rod 201, and the sleeve ring 203 and the hinge shaft 202 on each combined rod 201 are arranged in opposite directions.

[0026] When storing and transporting the bracket 2, pressure can be applied to the bottommost connecting rod 201 of the bracket 2 to bend it, causing it to deflect along the connecting ring 203 of the top connecting rod 201 via the hinge shaft 202. This will cause the bottommost connecting rod 201 to fold to the side that is attached to the connecting rod 201 above. Then, the other connecting rods 201 are bent in the opposite direction to form an "N" shaped fold, thereby folding and storing the bracket 2 and reducing its size for easy carrying.

[0027] Furthermore, the combined rod 201 also includes a connecting groove 2011, a connecting block 2012, and a stop block 2013. The connecting groove 2011 is located on one side of the combined rod 201, the connecting block 2012 is located on one side of the combined rod 201, and the stop block 2013 is connected to both sides of the connecting block 2012. The positions of the connecting groove 2011 and the connecting block 2012 on both sides of each segment of the combined rod 201 are opposite. The stop block 2013 is a trapezoidal block connected to the grooves on both sides of the connecting block 2012 by a spring, and the stop block 2013 cooperates with the grooves on both sides of the middle part of the connecting groove 2011. The fitting assembly includes a limiting groove 204 and a limiting block 205. The limiting groove 204 is located on the bottom side of the combined rod 201 away from the sleeve ring 203, and the limiting block 205 is located on the top side of the combined rod 201 away from the hinge shaft 202. The stop blocks 2013 are provided on both sides of the limiting block 205, and the limiting block 205 cooperates with the limiting groove 204.

[0028] Meanwhile, when the combination rod 201 is folded and attached to one side of another combination rod 201, the connecting block 2012 on one side will retract by abutting against the opening of the connecting groove 2011 through the abutment 2013, and then fit into the connecting groove 2011, so that the abutment 2013 moves to the groove position on both sides of the middle of the connecting groove 2011. The spring returns and pops out, so that the connecting block 2012 will be fixed in the connecting groove 2011 by the abutment 2013, so that its bracket 2 will not unfold on its own after being folded and stored.

[0029] When the final combination rod 201 is unfolded, the limiting block 205 will fit into the limiting groove 204 of another combination rod 201. Similarly, the connection is limited by the retraction and reset of the abutment block 2013, so that the combination rod 201 will not deflect on its own after unfolding.

[0030] The following is a detailed implementation process of this utility model. First, the theodolite for road surveying is installed on the base 1. Then, the base 1 unfolds into a triangular support frame through the bottom bracket 2, allowing the theodolite to be stably placed on the road for road surveying. When storing and transporting the bracket 2, pressure is applied to the bottommost connecting rod 201 of the bracket 2 to bend it, causing it to deflect along the connecting ring 203 of the top connecting rod 201 via the hinge shaft 202. This folds the bottommost connecting rod 201 to the side that is attached to the upper connecting rod 201. Then, the other connecting rods 201 are bent in the opposite direction to form an "N"-shaped fold, thus folding and storing the bracket 2, reducing its volume for easy transport. Simultaneously, when the combination rod 201 is folded and attached to one side of another combination rod 201, the connecting block 2012 on one side will retract by abutting the abutment block 2013 against the opening of the connecting groove 2011 and then fit into the connecting groove 2011, so that the abutment block 2013 moves to the groove position on both sides of the middle of the connecting groove 2011. The spring returns and pops out, so that the connecting block 2012 will be limited to the connection in the connecting groove 2011 by the abutment block 2013, so that its bracket 2 will not unfold on its own after being folded and stored. Finally, when the combination rod 201 is unfolded, the limiting block 205 will fit into the limiting groove 204 of the other combination rod 201, and the connection will be limited by the retraction and reset of the abutment block 2013, so that the combination rod 201 will not deflect on its own after being unfolded.
